I'm making a stand up comic bard and i came across lingering performance feat which means that I can end my bardic performance and its effects last for two additional rounds after. Doesn't this just mean I have 3x the amount of bardic performances per day? I could conceivably tell a joke for one round, end the performance as a free action, gain the effects for the next two rounds while I take other actions and then repeat. It seemed totally OP to me. Or is it that you can take other actions but the two lingering rounds count against my # of performances per day?
